three.js 三角体 贴图

// 引入Three.js库
import * as THREE from 'three';

// 创建场景
const scene = new THREE.Scene();

// 创建相机
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

// 创建渲染器
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 创建三角形的顶点
const geometry = new THREE.BufferGeometry();
const vertices = new Float32Array([
    -1.0, -1.0, 0.0,
     1.0, -1.0, 0.0,
     0.0,  1.0, 0.0
]);
geometry.setAttribute('position', new THREE.BufferAttribute(vertices, 3));

// 加载纹理
const textureLoader = new THREE.TextureLoader();
const texture = textureLoader.load('path/to/your/texture.jpg');

// 创建材质并应用纹理
const material = new THREE.MeshBasicMaterial({ map: texture });

// 创建网格并添加到场景
const mesh = new THREE.Mesh(geometry, material);
scene.add(mesh);

// 渲染循环
function animate() {
    requestAnimationFrame(animate);
    renderer.render(scene, camera);
}
animate();
